Silas R. Beane, Martin J. Savage
TL;DR
This paper extends an effective field theory to partially-quenched QCD, enabling more accurate lattice simulations of nucleon-nucleon interactions by providing necessary amplitudes for connecting simulations to real-world physics.
Contribution
It introduces a next-to-leading order partially-quenched effective field theory for nucleon-nucleon scattering, facilitating improved interpretation of lattice QCD results.
Findings
Derived partially-quenched nucleon-nucleon amplitudes at next-to-leading order.
Established the role of these amplitudes in relating lattice simulations to physical nucleon interactions.
Enhanced the theoretical framework for multi-nucleon lattice QCD studies.
Abstract
Nucleon-nucleon scattering is studied to next-to-leading order in a partially-quenched extension of an effective field theory used to describe multi-nucleon systems in QCD. The partially-quenched nucleon-nucleon amplitudes will play an important role in relating lattice simulations of the two-nucleon sector to nature.
